Ceramic&Exsev bearing series

More and more bearings are being used in extreme special environments, such as in a vacuum, or in a clean, corrosive, or heated place. In some cases bearings are required to be insu-lated or antimagnetic.

Applications of bearings in such environments are increas-ing in the field of state-of-the-art technology, e.g. vacuum equipment, aerospace equipment and semi-conductor produc-tion facilities. Bearings made of conventional materials and lubricants can hardly meet these new needs.

JTEKT has succeeded in developing a series of bearings for use in extreme special environments, having started from the study of the very basics of materials and testing of their performance under various severe conditions.

JTEKT has standardized the following bearings as the "Koyo bearing series".

¡

Exsev bearings for use in a clean environment Designed for use in a vacuum. The friction surface of the bearing interior is coated with solid lubricant (or soft metal). Bearings pre-lubricated with special grease are also available.

¡

Exsev bearings for use in a vacuum environment Produce insignificant contamination, provided with rolling elements and a cage made of self-lubricating materials. Optimal for use in environments which need to be clean.

¡

Ceramic bearings Ceramic rings and rolling elements (silicon nitride Si

) ensure excellent performance in various extreme special environments.

¡

For details, refer to JTEKT separate catalog "Ceramic bearings and bearings for extreme special environments" (CAT. NO. B2004E).

The chart below summarizes the EXSEV bearing series and the conditions in which each operates successfully. Materials and lubricants which are resistant to certainspecial conditions are listed in Tables 1 and 2. Major Koyo EXSEV bearing series made of these materials and lubricants are listed in Table 3.

[Notes] 1) A larger Young's modulus indicates higher rigidity.

2) A smaller coefficient of linear thermal expansion indicates a greater dimensional stability under heating.

2) The corrosion resistance column shows general

evaluations.

Marks """ and "#", respectively, denote

"excellent", "good", and "fair".

Refer to Table 1 for the corrosive materials

concerned.

3) These soft metals are applied by the special

ion plating method JTEKT developed, so that

they feature excellent bonding strength,

extending the service life of bearings.

4) When higher corrosion resistance,

nonmagnetism and heat resistance are

required, Full Ceramic Bearings should be used.

Please consult with JTEKT for details.

Ceramics can also be used to produce many

types of bearings, such as angular contact ball

bearings and cylindrical roller bearings.

5) These evaluations indicate the cleanness

around the bearing, or in the equipment interior.

Cleanness is largely dependent on the amount

of dirt produced by operation of the bearing.

The suffixed numbers refer to amounts of dirt,

and the smaller the number is, the less dirt

produced by the bearing.

[Ex.] Class 10⋅⋅⋅⋅⋅⋅⋅there are less than 10

particles 0.5 μm or larger in diameter in

a 1-cubic-foot space.(as specified in

USA standards FED-STD-209D.)

Life of EXSEV Bearings EXSEV bearings, lubricated with a solid lubricant, are usually used under relatively light load conditions, such as 10% of their static loadratings or less. These bearings can maintain stable performance as long as the solidlubricant is maintained. Once the lubricant wears out, metallic contact occurs, which increases rotational friction torque and shortens service life.

Service life depends on use conditions. At present, it is notpossible to predict their service life under varied use conditions. However, based on a variety of experiments and tests, JTEKT has established an experimental formulae to predict the lives of bearings.The formulae is described in the following subsections for reference only.

(1) Life of MG bearings consisting of silver-coated balls

The life of MG bearings (JTEKT serial number, SE...STMG3) can be predicted according to the following formula;

where,

(2) For bearings coated with PTFE or special polymeric fluoride

For those bearings coated with PTFE (MP7) or those coated with the special polymeric fluoride (PR), the following formula gives their mean life for reference only. (See Fig. 3.8.)

where,

L

av : Average life, hb2 : Lubrication coefficient 6 for bearings coated with PTFE 42 for bearings coated with special polymeric fluorideCe : 0.85 times the basic dynamic load rating of steel bearings

Lav = b2 ⋅ (Ce/P) d × 0.016667/n ⋅⋅⋅⋅⋅⋅⋅⋅⋅⋅⋅⋅⋅⋅⋅⋅⋅⋅⋅⋅ (2)

Fig. 1 Mean life of Coated Bearings

(3) Ceramic bearing service life

Ceramic bearings are used for a variety of pur-poses, and their specifi-cations differ case by case. Therefore, there is no common system for estimating their service lives. The estimation of full ceramic bearing service life is especiallydifficult at present for theoretical reasons, and requires further study. JTEKT estimates the full ceramic bearing service life on a case by case basis according to the customer request, based on experience and experi-mental data.

For hybrid ceramic bearings, in many cases the conventional equation (2) below based on rolling contact fatigue is used to estimate service life, where grease or oil can be used for lubrication and, at the same time, bearings are required to be insulating and antimagnetic, or to be highly rigid and have excellent high-speed performance. This equation is called the corrected rated life estimationequation. (refer to p. A 26.)

¡In an environment where a lubricating film is formedproperly, the bearing characteristic coefficient a2 is expected to be equivalent to or larger than that of conventional steel bearings. How-ever, given current conditions, coefficient a2 is counted as : a2 = 1.

Basic dynamic load rating C is treated as being equivalent to that of steel bearings of the same type and size. ¡When a satisfactory oil film is formed, the operating condition coefficient a3 is counted as : a3 > 1.

K-series super thin section ball bearings

Koyo K-series super thin section ball bearings were developed to meet current engineering needs for thinner, lighter bearings. They are used extensively in automation and labor saving equipment, such as industrial robots.

These bearings are sorted into nine dimension series according to cross-sectional area.Those of the same dimension series have an equivalent cross-sectional area irrespective of the bore

diameter.They are available in three types that differ in structure.

■

Deep groove type

Carries radial load, axial load in both directions, and combined loads.

■

Angular contact type

Has a 30° contact angle, and carries radial load and axial load in one direction.Two bearings areusually used together facing one another.

■

Four-point contact type

Has a contact angle of 30° both to the right and to the left.Able to carry axial load in both directions. Also able to support moment and radial loads.

Bearings for machine tool spindles

(for support of axial loading)

JTEKT supplies double direction angular contact thrust ball

bearings and ACT type matched pair angular contact ball

bearings which are used with machine tool spindles to support

axial loading.

These bearings were developed to meet needs which have

grown as machine tool spindle rotation has become faster and

more accurate.

Several dimension series are available for selection

according to operating conditions.

For details, refer to JTEKT separate catalog "Precision Ball

and Roller Bearings for Machine Tools" (CAT. NO. B2005E).

See also the catalog for high ability bearings, CAT NO.

B2006 for High Ability Ball Bearing Series Angular Contact

Ball Bearings for Machining Tools.

(Reference)

Major bearing types which are used to carry radial

loading of machine tool spindles are shown below.

For further details, refer to the specification table

for each type.

[Notes]

1) These bearings are usually used in arrangement with a double-

row cylindrical roller bearing which carries a radial load.

There are four arrangement types (

q

to

r

) as follows :

q

Mounted with an NN30K tapered bore bearing or with an NN30

cylindrical bore bearing. The tapered bore bearing is combined

at its smaller side.

w

Mounted with an NN30K tapered bore bearing, which is

combined at its larger side.

e

Mounted with an NNU49K tapered bore bearing or with an

NNU49 cylindrical bore bearing. The tapered bore bearing is

combined at its smaller side.

r

Mounted with an NNU49K tapered bore bearing, which is

combined at its larger side.

2) The overall width "2

B

" of ACT0 DB and ACT0B DB bearings is

equivalent to dimension "

C

1

" of 2344B bearings. Therefore,

when a 2344B bearing is replaced with an ACT0 DB or ACT0B DB

bearing, change the width of spacer "A" only.

No change is necessary to the spindle or housing dimensions.

Characteristics

¡

Supports axial loading in both directions.

Highly rigid in the axial direction.

¡

Bearings with a larger contact angle

feature higher rigidity, while those with a

smaller contact angle feature better

high-speed performance.

¡

For support of axial loading only.

Negative tolerances are specified for the

outside diameter.

¡

Excellent high-speed performance is

achieved

because of the small contact angle.

¡

Interchangeable with 2344 B series

bearings.

Precision ball screw support

bearings and bearing units

■

Support bearings were developed to support precision ball

screw shafts. They have the same structure as angular

contact thrust ball bearings with a contact angle of 60°.

¡

Have a large axial load

carrying capacity. Also able

to carry a certain degree of

radial load.

¡

Highly rigid in the axial

direction.

¡

Starting torque is small.

■

Support bearing units consist of the bearings described above and a precisely processed housing.

Units with a Koyo precision ball screw are also available.

Full complement type cylindrical

roller bearings for crane sheaves

Crane rope sheaves and running wheels which are

operated at low or medium speed are generally equipped with

full complement type cylindrical roller bearings because the

operation of these machines involves heavy, impact loading.

These bearings are divided into shielded and open types.

The shielded type is often used with the outer ring rotation.

■

Shielded type

¡

The shielded type was developed for use with rope

sheaves. It is shielded, non-separable and pre-lubricated with grease.

¡

Bearings with locating snap rings around the outer ring can be positioned and fit to sheaves with

ease.

¡

The bearing surface is coated with phosphate for rust prevention.

■

Open type

¡

Open type bearings are further divided into those used on the fixed side and those used on the free

side. The former carry axial load in both directions. The relative position of the latter's inner ring

and outer ring can be adjusted by moving them along the axis.

¡

Open type bearings are separable because the outer ring divided into two annular pieces in a

Rolling mill roll neck bearings

Rolling mill roll neck four-row cylindrical roller bearings and tapered roller bearings are designed to achieve the maximum load rating capacity in a limited space.

■

Four-row cylindrical roller bearings

¡

Suitable for high-speed rotation. Thin section designs are also available.

¡

The inner ring raceway surface and the roll can be fin-ished simultaneously after the inner ring is mounted on the roll neck. This feature is useful in improving rolling mill accuracy.

■

Four-row tapered roller bearings

¡

Suitable for low- and medium-speed rotation.Available in both metric and inch series.

¡

The internal clearance is preadjusted, facilitatingmounting.

Bearings for railway rolling

stock axle journals

Bearings used to support rolling stock axle journals are

required to be very strong and, at the same time, to be small

because of limited space.

Double-row bearings that are larger in width than general

bearings are popular in that they are compact and have high

load ratings.

■

Cylindrical roller bearings

¡

Feature good high-speed performance, and can be

maintained and inspected easily because of their

separable structure.

Most commonly used bearing.

¡

Those with a rib next to the inner ring are able to support

not only radial load but also a certain degree of axial load,

so that a ball bearing is not required to accommodate the

axial load.

■

Sealed type cylindrical roller bearing units and tapered

roller bearing units

¡

Maintenance-free : pre-lubricated with grease and

provided with oil seals.

¡

Can be used with a simplified axle box, or with an adapter

instead.

¡

The inch series axle bearing units (ABU) are as specified

in the "association of american rail-roads".

Linear ball bearings

Linear ball bearings have an outer cylinder and acage with three or more elliptic raceways inside. Balls are aligned on these raceways.

Standard type Clearance adjustable type Open type

Suitable for a wide range of applicationsand widely used in practice.The upper-class type is used for generalpurposes. The precision-class type isused when the bearing is required to behighly accurate.

Flanged type

Can be fit quickly, andhelps make equipmentsmaller and lighter inweight. Helps reduce cost.

Sealed type

One or both side(s) is/aresealed with special syntheticrubber so that foreign materialcannot enter the bearing whilethe grease is kept from leaking.This sealing can be provided onall bearings of the standard,clearance adjustable, open,and flanged types.

The outer cylinder and side plate are slitaxially so that the clearance between thebearing and shaft can be adjusted.Together with the use of a boreadjustablehousing, a no-clearance state or light-preloaded state can be realized withoutfitting.

The outer cylinder and side plate eachhave a slit which is equivalent in sizeto a recirculating ball row raceway, sothat the bearing does not interferewith a shaft strut during operation.This type is suitable for use with very longshafts. The bore diameter is adjustable.

Linear ball bearing service life

Linear ball bearing service life refers to thedistance that the bearing travels until the outercylinder, balls or shaft become damaged because of rolling contact fatigue from repeated stress. The basic dynamic load rating refers to themagnitude of a constant load which makes abearing's service life end after it travels a distance of 50

km

. The linear ball bearing service life and thebasic dynamic load rating bear the relation shownbelow :

Shaft surface hardness is closely related to running performance. In general, it is best for the hardness to be 60 thru 64 HRC. If the hardness is 60 HRC or lower, the basic dynamic load rating (

C

) should be corrected by multiplying it by the appro-priate hardness coefficient selected from Table 1.

¡

Ball row arrangement and load rating

The basic load ratings given in thespecification table are those measured when a load is applied directly above a ball row (

Q

1

). When the load is applied between two ball rows, the load ratings become larger (

Q

2

). Table 2 lists the ratios of

ratings to

ratings.

Recommended fits for linear ball bearings

Table 3 lists the recommended fits for linear ball bearings. When a bearing is mounted with a housing, the normal clearance fit should be selected. When the application is highly precise or special, the transition fit should be selected.

For the clearance adjustable and open type bearings, it is best for the shaft diameter to be smaller than the ball complement bore diameter lower deviation, and for the housing borediameter to be larger than the bearing outside diameter upper deviation.

■

Linear ball bearing clearance

Linear ball bearings provide linear motion smoothly with little wear when the clearance is 0.003 to 0.012

mm

. However, when clearance increase due to wear is considered critical, e.g. when the bearing is provided to press die sets, precision machine tools or precision testers; when the bearing becomes unable to slide because of moment; or when smooth bearing operation is needed with no clearance provided, the clearance is adjusted to zero or negative. In such a case, shafts generally need to be mounted by "selective fitting." They should be handled carefully so as not to be preloaded excessively. As Fig. 1 shows, the clearance of bearings with numbers SDM 6 thru SDM 10 can be easily set to

zero or negative, by adjusting one of the three ball rows with a bolt. Consult with JTEKT on the gauging of linear ball bearings and shafts which should be mounted by "selective fitting," as well as on the whole design of shafts.

Locknuts, lockwashers & lock plates

Bearings are often fit to a shaft with an adapter sleeve,

locknut, lockwasher or lock plate.

These accessories make it easy to attach and remove

bearings.

They are standardized in JIS.

¡

Locknuts are standardized such that they can be used with

either adapter sleeves, withdrawal sleeves or shafts.

¡

Lockwashers and lock plates are used as locks on locknuts.

Lockwashers are used with bearings of bore diameter

number 40 or lower. Lock plates are used with those of bore

diameter 44 or higher.
